Does experimental_ble_app_uart not work without Flow Control?

I am trying to make the experimental_ble_app_uart for s110 work using SDK 7.2. It works fine without any modifications, but when i turn off Hardware Flow Control in the UART_init() i am not able to send anything. Does anyone know what the problem is?

The flow control is enabled BOTH on the ble_app_uart which is a peripheral device AND also on the application which acts as central and connects to this experimental_ble_app_uart.

You have to disable it on both sides (i am not sure how to disable this on app)

Out of curiosity, why are you trying to disable flow control?

I am trying to connected an s120 device with the s110 device with direct UART contact, and then make several of these units, and trying to make a hop-by-hop network of sorts. Told it was easier to just pass on the flow control since the baudrate wasn't as high. As i understand it, there really isn't any need for flow control when the project doesn't do much more than the basic example. But I am new to this, so if you have any comments feel free to speak up! Anyway thanks for the help, i guess as long as no devices uses flow control it should work?
